The investigators will query any hospitalizations or emergency room visits over the past month and reasons for those visits at the baseline, 6 and 12 week follow-up visits. Serum calcium and vitamin D levels will be measured t 6 and 12 weeks and anyone with serum calcium levels ≥ 10.6 meq/L and/or a 25(OH)D level ≥ 80 ng/ml will stop treatment. All adverse events will be reported to the Loyola University Chicago Health Sciences Institutional Review Board. A data safety and monitoring board will review all data collected after completion of the 6 week visit to ensure safety of the study.
